Question about Toshiba 14" LCD Monitor

Open Question

Toshiba monitor on-off

I have a Toshiba flat-screen monitor form my home computer. (I'm at work now, so I don't have the model # handy.) A few nights ago, I turned the monitor off to save energy. When I turn it back on, the on-off switch flashes blue about every other second, but the monitor does not light up. I tried jiggling the mouse, hitting keys of the keyboard, and -- ultimately -- turning off and restarting the computer. No luck. Any ideas?

SOURCE: Laptop monitor blacks out, but when you hit the toggle....

Sounds like you need a new Switch. Oxidation has probably built up in the switch. It can be fixed. Probably shop around for a certified tech who can replace it. The switch is cheap, Labor is starting around $65 - $90. You said you can faintly see the desktop. This is the invertor board inside the LCD assembly that causes this. Again if it needs to be replaced, the invertor is fairly inexpensive, labor isn't. The technician that ckecks out the laptop can determine what it needs. Yea, your right, it is a good laptop and it is worth fixing. Just a heads up, if the tech says you need a new motherboard, he's lying, find another tech.

SOURCE: screen stays black on startup of toshiba satellite L300

have you tried either switching between external and internal monitor usally Fn + F5 on toshiba or try plugging a monitor into the back and see if it displays.
if you get a display on the external monitor then its probably a screen or inverter fault if you donot get a display to an external screen then it is likley t be the graphics on the board itself.
hope this helps

Older-model Toshiba TV shuts off by itself


There is a large sand filled resistor on the main board close to where the power cord attaches that cracks. This will stop power until it cools enough to make the connection then heats up rapidly to open it again. It may be worth the trouble if you're handy with a soldering gun and can get the back off the TV. If not then I'd consider getting a flat screen.

Hi the sceen goes black when it is switched on for ten minutes if I switch it off for a few minutes the sceen comes back on. It will then shut off again after a few minutes. Thanks Alan


This is due to the inverter for the backlight, or the backlight itself going bad. You are going to be better off replacing the screen unless you are handy with electronics.

I have a Dell SE198WFP Flat Panel Monitor, screen goes black?


The LCd panel may be damaged and will cause this problem.

Another thing is overheating of the GPU.

The LCD signal receiver can be goign on you.

The is also the possibility of a faulty inverter.

Only thing to do is service or replace. Test the unit on another computer, if you don't get the issue there then you know its a problem with the PC.

The monitor startup and few seconds later it turn


You are going to have to open up the monitor, please read below if you are going to DIY.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My laptop toshipa A135 has died. when i push power


In this case you need to check the inverter, defective inverter will cause the following symptoms:
No Display
dim screen
Screen Flash on and Off between 1/2 to a few seconds

Actually you need to replace the inverter buy a new inverter which is compatible to the old one. Installing the inverter is easy, it does not require any technical skills. In fact, it is a lot easier then changing the I/O Card in your PC System because there is no driver ( Software) Involve.
Tools:
Philips screw driver
Small Flat screwdriver

Preparation:
Make sure your have enough space on your desk and it must be clean.
Disconnect AC Adapter and Remove Battery from Laptop Computer.

Procedures:
This procedure is based on Toshiba Satellite A105-S4284 (with 15.4 inch Screen)
Removing the front bezel on Laptop screens is easy. Usually, these screws are covered by small rubber pad; so, all you need to do is remove these rubber pad and screws. To do this procedure you can find some instructions as shown on the next few photos to the link that i can provide below.

Flat screen monitor functioning strangely


Sounds like there maybe bad caps on the power board in the LCD. Try a different monitor on your computer and if the known working monitor comes on with the computer and behaves properly then you know its a problem with your original monitor. If the known working monitor acts strange as well then you know its a problem with the video card. Let me know what happens.
